Im thinking about buying the Saitek Pro Flight System but before I do is there a tutorial youtube, website or anywhere where I can get a tutorial on how to use the mixtures and such.

Thanks Wink

As soon as I get caught up on some model projects.. I'm going to add some lessons re: complex (gear/flaps/constant-speed prop) planes.. and instrument flight training...

Awesome!

No rush, I should be getting the yoke and throttle by christmas but I thought I would learn before.
Just contact me when its out..
Thanks! Cool

Start using the mixture when at around 2000 feet or above in FS.

Lean (pull the mixture back) until the EGT (Exhaust Gas Temperature) peaks, then push it forward a little notch.

All depends on the aeroplane being used.

Where do I find the EGT?

There'll be a gauge, near the tachometer (RPM) and the like, that reads EGT.

On some planes, it'll be a combined gauge with two needles, one showing EGT, and another something else.

I'll quote you on this one:

I've seen oil temp more often....

NVM though Tongue

You're quite right. Oil temp/EGT are combined most often; I was thinking of a split MP/Fuel flow gauge.

But then again I haven't flown a piston aircraft for 18 months! Grin

A fair general rule of thumb, which works on any piston airplane with a tachometer, is to "lean for best power". In other words, back off the mixture until you see a slight increase in power, then stop when you see the power level off.

That's the method I usually use in RL, as I don't always get a plane with an EGT. Seems to work OK.

Some engines may not really like that method, so if there is an EGT, it's best to use that (I guess), or in the absence of an EGT, use the tach but keep an eye on the engine temps (oil temp, cylinder head temp if available).

I rarely get single engine piston aircraft to an altitude where precise leaning is all that critical, as far as power goes. I'm alway shooting for that sweet-spot where fuel-econmomy meets not fouling a plug Cheesy

Anything under 3000msl and I just back the mixture out a little.. kinda in one motion as I reduce power and am trimming the elevator.

At higher altitudes I use a method similar to Rotty's... SLOWY lean until there's an audible drop in RPM (watching the tach too), and then richen a couple twists.

In MSFS, it's really weird (and unrealistic), but you can lean by peaking the fuel flow... and then lean a hair more Roll Eyes

Edit : However.. the Goose has an accurate and responsive EGT gauge (digital).. and can be used for relaistic leaning.

Well my Grandpa is getting his yoke, throttle, and rudder pedals shipped to him right now. I wont have mine till Christmas but he said he would let me borrow them for a month so ill have them all October I might have to wait on a tutorial becuase im so off Grin
